Description

  The present invention relates to a banknote recognition apparatus that is mounted on a vending machine or the like and recognizes and accepts inserted banknotes, and more particularly, to a banknote identification apparatus that prevents banknote jamming in the identification section.

  As such a conventional banknote discriminating apparatus, there is known a banknote discriminating apparatus having an identification structure as described in Japanese Patent Application Laid-Open No. 7-105427 (Patent Document 1) previously published. In the banknote identification device described in Patent Document 1, the leg piece normally protrudes into the banknote transport path to prevent the banknote from passing through, and the banknote is passed by immersing the leg piece from the transport path when the banknote is inserted. It includes a bill fraud prevention mechanism with an allowed pullback prevention mechanism, and magnetic sensors and optical sensors are arranged in the same row in the bill transport direction corresponding to at least one of the leg pieces. .

  According to this, according to the position of the leg piece of the pullback prevention mechanism, the banknote is divided and cut in the insertion direction, the string is attached to the edge of each cut piece, and each cut piece is weakly bonded. The original form of the banknote is restored by bonding together using an adhesive piece, and in this state, the modified banknote is inserted into the transport passage, and immediately after the receipt is completed, the banknote is connected by a string. When trying to execute an illegal act of dividing and pulling back from the banknote, the magnetic resistance and transmitted light rate are detected by the magnetic detection sensor and the optical sensor at the spliced portion of the spliced bills. Since it differs from that of regular banknotes in the mating portion, the acceptance of the altered banknotes is rejected and sent back to the insertion slot, thereby preventing illegal acts.

Japanese Unexamined Patent Publication No. 7-105427

  By the way, in the banknote identification device described in Patent Document 1, when the magnetic resistance characteristic of an accepted banknote is detected by a magnetic detection sensor, the banknote is pressed against the magnetic detection sensor by a pressing member in order to accurately detect it. The magnetic resistance is configured to be in close contact with each other. Here, the magnetic detection sensor and the pressing member are normally pressed against each other by a spring or the like that biases the pressing member toward the magnetic detection sensor. And when a banknote is thrown into a banknote identification apparatus, the front-end | tip will be conveyed so that it may be pushed in into the junction part of these magnetic detection sensors arrange | positioned on a conveyance path, and a press member. At this time, since the leading edge of the banknote enters the joint so as to push away the pressing member, the conveyance resistance increases. In addition, when the inserted banknote is rejected based on the detection results of these magnetic detection sensors, the rear end of the banknote is similarly pushed into the joint between the magnetic detection sensor and the pressing member. Then it is transported in the opposite direction and returned to the slot. In this case as well, the conveyance resistance similarly increases. If it does so, when the edge part of a banknote passes the junction part of a magnetic detection sensor and a press member, the conveyance resistance will become large and banknote jam will occur easily. In particular, when a sticky tag such as a tag with a hook or a wet tag is inserted, there is a problem that the frequency of clogging is increased because it cannot pass through the joint between the magnetic detection sensor and the pressing member. there were.

  In order to cope with such a problem, the present invention reduces the conveyance resistance when the end of the banknote inserted into the banknote recognition apparatus passes through a magnetic detection sensor provided on the conveyance path, for example, An object of the present invention is to provide a highly reliable banknote identification device capable of preventing the banknotes from being jammed even if the banknotes to be played are weak cards such as bills and wet tags.

  In order to solve the above-mentioned problems, the invention according to claim 1 includes a bill insertion slot, a bill conveyance path extending continuously from the insertion slot, and a conveyance means for conveying the bill along the conveyance path. A magnetic sensor that is provided on the transport path and detects a magnetic characteristic of the banknote to be transported, and a banknote that is provided to face the magnetic sensor and that is transported on the transport path is pressed against the magnetic sensor. A bill discriminating apparatus comprising: a sensor presser plate for biasing; and a bias release means for releasing the bias of the sensor presser plate, wherein the bias release means is a bill that is transported on the transport path. When the end of the sheet enters the magnetic sensor, the urging of the bill by the sensor pressing plate is released.

According to this, when the front end of the banknote transported on the transport path enters the magnetic sensor, the biasing of the banknote toward the magnetic sensor by the sensor pressing plate is released by the biasing release means. Therefore, the conveyance resistance when the tip of the banknote passes over the magnetic sensor can be reduced.
Moreover, the invention which concerns on Claim 2 is the banknote identification device of Claim 1, and always closes the said banknote conveyance path | route, and when a banknote is inserted from the said insertion port, or acceptance of the banknote is refused. A paper path shutter for preventing the withdrawal of banknotes when the paper path is returned, and the urging release means attaches the banknotes by the sensor presser plate in conjunction with the opening operation of the paper path shutter. It is to release the force.

  According to this, when a bill is inserted from the insertion slot, or when the acceptance of the bill is rejected and returned, the magnetic force by the sensor presser plate is interlocked with the opening operation of the conveyance path shutter. Since the urging of the bill toward the sensor is released, it is possible to reduce the conveyance resistance when the end of the bill passes over the magnetic sensor. Further, since the urging release means releases the urging of the bills by the sensor presser plate in conjunction with the transport path shutter, the configuration can be simplified by using only one of these driving means.

  As described above, according to the first aspect of the present invention, when the leading edge of the banknote transported on the transport path enters the magnetic sensor, the bias of the banknote toward the magnetic sensor by the sensor presser plate is applied. Since it is released by the force release means, the conveyance resistance when the tip of the bill passes over the magnetic sensor can be reduced, so that the clogging when the end of the bill enters the magnetic sensor is prevented. Can be prevented. Accordingly, it is possible to provide a highly reliable banknote identification device.

  According to the invention of claim 2, when a bill is inserted from the insertion slot, or when acceptance of the bill is rejected and returned, the sensor press plate is interlocked with the opening operation of the conveyance path shutter. By releasing the bias of the bill toward the magnetic sensor, the conveyance resistance when the end of the bill passes over the magnetic sensor can be reduced. When it is done, banknote jams can be prevented. Further, since the urging release means releases the urging of the banknotes by the sensor presser plate in conjunction with the transport path shutter, it is possible to simplify the configuration by uniting those driving means. Can be made cheaper. Therefore, this makes it possible to provide a banknote identification device that is inexpensive and highly reliable.
